Eintopfsynthese neuer Tricarbonylchrom‐Komplexe von Makrocyclen und ‐bicyclen mit Areneinheiten: Synthese und Struktur eines CrCu‐Cryptats

Abstract

Drei „äuß;ere”︁ Cr(CO)3‐Einheiten und zwei „innere”︁ CuI,−Ionen enthält das dikationische Cryptal 1, das aus [Cu(CH3CN)4]ClO4 und dem entsprechenden Makrobicyclus hergestellt werden kann. Dieser ist in einer Eintopfreaktion aus Terephthalaldehyd‐tricar‐bonylchrom und Tris(2‐aminoethyl)amin in 75% Ausbeute zugänglich.

Synthesis and Structures of Cadmium(II) Complexes with (η6‐Benzenecarboxylate)tricarbonylchromium

“…It was shown in 1990 that (benzoic acid)tricarbonylchromium and its derivatives form extended arrays in which the molecules are linked by hydrogen bonds. [7,8] Moreover, [(η 6 -arene)tricarbonylchromium] complexes have been used to form bimetallic complexes, [14,15] mesomorphic materials, [16] polymers, [17,18] macrocycles, [19] and receptors. [20] Recently, Kaye 3 }], which is a porous metal-organic framework.…”

Synthesis and Structures of Zinc(II) and Cadmium(II) Complexes with (η6‐Benzenecarboxylate) Chromium Tricarbonyl and Pyrazole Derivatives

“…In the latter concept an organometallic compound such as ferrocene is used as part of the ligand scaffold 8. In this context, also [( η 6 ‐arene) chromium tricarbonyl] complexes were used to form bimetallic compounds,9 mesomorphic materials,10 polymers,11 macrocycles,12 and receptors 13. ( η 6 ‐Benzoic acid) chromium tricarbonyl, which was already reported in 1958 by E. O. Fischer ,14 is known to form extended arrays in which the molecules are linked by hydrogen bonds 15.…”

Hydrogen bonding networks in [(η6‐arene)Cr(CO)3] complexes

“…They have found applications in asymmetric synthesis [7], catalysis [8,9], Fourier transform infrared spectroscopy (FTIR)-readable molecular sensors [10], and for the preparation of non-linear optic (NLO) materials [11]. Moreover, [(η 6 -arene)chromium tricarbonyl] complexes were used to form bimetallic complexes [12,13], mesomorphic materials [14], polymers [15,16], and macrocycles [17]. Recently, Long and Kaye [18] reported on the synthesis of [Zn 4 O{(1,4-benzenedicarboxylate)Cr(CO) 3 ], which is a porous metal organic framework.…”
